That’s the best tip I’ve seen in a long time I’ll be doing that from now on thanks for sharing

Thanks, Jim, for a clever and elegant solution. Just for the record, although we don't need math for this problem, we do need math. :)

A very early Analog Computer - also known as a 'Sector' uses this. You can use a ruler to divide a board much the same way, just select a number of inches equal to (or divisible by or a multiple of) the number of divisions, lay the ruler/tape across the board at an angle so the zero point and end point touch the edge then mark at the inch marks (or centimeters, fingers or whatever). Does not work as well for large numbers of divisions but works well for 1/3, 1/5, 1/7 divisions that common math just can't do.

Great tip.
Alternatively, instead of creating a grid, there are all kinds of repeating patterns one can utilize. One time I laid out my board I needed to divide across my porch deck. Since I built it myself, I knew the spacing was adequate for what I was doing. I have a self-healing cutting grid mat for smaller situations but have also used a sheet of paper.

Learned that one in the Navy in Damage Control training for shoring.

Lovin' these little tips Jim. So simple but my brain never thought of them JimE

Great tip! Thanks
I have the perfect piece of 1/4 plywood for that....

Step 1 in dividing up a board into equal sections without measuring - measure out equal one inch spaces on a board. XD =)

Skip the scrap & just use a tape measure directly. Clamp the end so the end is exactly lined up with a mark, angle until the other end is also lined up, clamp, and mark away. Can use full inches, half inches, quarter inches... doesn't matter. (And you don't need a chunk of scrap wood turned into an ungraduated ruler.)

I always follow you videos.
I find your explanations clear and precise.
You often use unique techniques to make the project simpler.
Sorry, but I am sure, dividing a board in equal parts is measuring which involves math. In fact I'm sure that one inch spacing involves a number.
Was that a measuring tape on your bench.
What you are doing is using geometry - which is indeed math!
We, math teachers, have enough of a problem combating math phobia.
I know you were trying to be humorous, (as am I), however, do you think building things with can happen without math?

Still a fan!
